I think you want the "right angled" connection to turbo pressure side. See the following note from quasi, and check his page at http://quasimotors.gar.net/hooter.htm
This makes a TON of sense to me!
Some question the installation of my valve (they say it's installed backwards), but I'm sure that mine is installed correctly. I think the question arises because of a drawing on the Townsend import site. I can't quite decode that drawing - maybe it's for a 900. Mine is installed correctly for the 91 9000, though. Then piston moves back toward the end where the vacuum line attaches. That means you don't want turbo pressure pressing on the piston at the opposite end (because that would force the valve open), so that connection goes to the intake (low pressure) side. The 90 degree connection goes to the metal inlet pipe, which carries turbo pressure. Turbo pressure will then be applied to the "back" side of the piston, meaning that the piston will be forced closed rather than open, until vacuum is applied to the vacuum line.
